SECIFICATION forming part of Letters Patent No. 743,299, dated November 3, 1903.

Application led January 9l 1903. Serial No. 138,336. (No model.)

To a/Z'Z whom t may concern:

Be it known that I, FRANK C. LEWIS, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee andv State of Wisconsin, have invented certain new and usefullmprovementsin Pumps; and

I do hereby declare that the following is a` into the consumers vessel, the quantity being measured in a dome in said pump, therev by doing away with the several measures required ordinarily, which for sanitary reasons as well as a saving of time is greatly to be desired; and it consists in certain peculiarities of construction and combination of parts, to be fully set forth hereinafter with reference tothe accompanying drawings, and subsequently claimed.

The drawing illustrates an elevation of my improved pump, with parts broken away and in section, so as to best show the invention, a portion of the barrel being broken out for convenience. v

Referring by letters to the drawing, A is a barrel, which is preferably made of wood, so as not to be aected by acid, and is of such length and diameter that it may be readily inserted into a Cask through its bung, its

lower end resting upon the bottom of saidV cask, with the discharge-spigot B a sufficient distance above the head of the latter so as to admit of a vessel being placed thereunder; A

The barrel A at its lower end is provided with recesses a, through which the liquid provided with a central recess d, that is nor-4 mally closed by a glass ball e, confined within the cage F.

The barrel A terminates with a square head G, into the central here of which is detachably tted the neck of a transparent dome"A H, this dome having its top slightly concaved, with a central opening f larger in diameter than the pump-rod E, which passes thereglllrough and terminates with a suitable han- Close to the neck of the dome H and comm unicatin g therewith is the wood en spigot B, which is driven into the head G, -as shown.

It is obvious that when the pump-rod is reciprocated on its upward stroke it will lift the ball D from its seat and draw in acharge of liquid, andwhen reversed said ball will close the hollow plug C, this causing the ball e in the cage F of the pump-rod to lift and allow the liquid to pass through the cage, where it is retained above the sucker, this operation being repeated until the pump has filled the dome or the desired amount has 4been raised therein, it being in plainsight of necessary to prevent an air-cushion at its top, and for this reason, as previously described, I make the opening flarger than the pump-rod, so that the -air may escape, and should the liquid slightly overtiow it would be caught in the concave top and drain back into the dome when the discharge-spigot is opened.

It is obvious that any size dome may be used, or, as shown, I may use onelarge enough for all purposes and provide the same with graduation-marks to indicate various quantities usually sold.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

l. In a pump, a pump-barrel, atransparent dome detachably tted into'the head of the barrel, openings at either end of said dome, a pump-rod adapted to be reciprocated through said openings and of less diameter than the latter, asuction-valve at the lower end of the pump-rod, a check-valve located at the bot- IOC tom of the pump-barrel and a spigot in oomrel, and a spigot inoommunication with the munieation with the lower opening of the neck of the dome, substantially as set forth. dome, substantially as set forth.
